The correct option is A Both A and R are true and R is the correct explanation of A.
Mitochondria and chloroplasts are called semi-autonomous organelles because they have their own DNA, mRNA, tRNA, ribosomes and they replicate by binary fission so they are said to be self governing. Semi-autonomous means they are in a symbiotic relationship with the cell and have evolved to become part of it.
